Hi thereWell I actually had a good experience with vitex. I took if for about 1 to 2 months not quite sure but I do know that it help me get pregnant. Unfortunately it was a chemical pregnancy but it helped me ovulate and get pregnant.I don't blame Vitex for the early miscarriage. I took it for a few months with out any problem but if I had one negative to thing to say about it is that you have to be careful how much you take and its recommended you take the exact amount said on the bottle because to much of it can cause some dark side affects such as bad mood swings, depression is worse on women who already have depression ant stuff like that. Otherwise the product is great and I recommend it. Also, its ok to take it if you end up pregnant using it - it's adviced to conitnue taking it and slowyg ween off.
